将Solr与Nutch问题结合起来
我正在跟随一个来自的教程。我已经分别安装了solr和nutch，它们都工作正常。当我必须集成它们时，问题就来了。从这个站点上的早期帖子中，我了解到模式文件可能存在一些问题。正如tut中提到的，我将nutch的schema.xml复制到solr的schema.xml，并重新启动了solr。由于配置问题，solr已停止。因此，我只是将每个文件的内容与现有内容一起复制到另一个文件中。现在（以及之前）我得到了这个错误：将Solr与Nutch问题结合起来,solr,nutch,Solr,Nutch,我正在跟随一个来自的教程。我已经分别安装了solr和nutch，它们都工作正常。当我必须集成它们时，问题就来了。从这个站点上的早期帖子中，我了解到模式文件可能存在一些问题。正如tut中提到的，我将nutch的schema.xml复制到solr的schema.xml，并重新启动了solr。由于配置问题，solr已停止。因此，我只是将每个文件的内容与现有内容一起复制到另一个文件中。现在（以及之前）我得到了这个错误： Indexer: starting at 2014-08-05 11:10:21 I

可能是由于某些版本的差异，教程建议复制conf/schema.xml，而在这个特定版本的solr中，应该复制文件schema-solr4.xml，然后在第351行中添加：
java-jar start.jar
